 Tatsu Masuda, you are one of Japan's foremost experts on energy. We are clearly in a period of climate change. How do you decarbonize energy? I think the most important thing is to decarbonize our mindset as well, because everything comes from our brains and behaviors, but there is an encouraging science, because there are very sound and global competition for better technology to decarbonize energy systems, and it's taking place in every part of the world. Does that include carbon capture and storage for coal? It's a long-term target, but that's going to be really one of the options. We really can't decarbonize without CCUS. Why has it taken so long, though? I mean, they've been trying for decades now. The major reason is there is only one way credible today that is enhanced oil recoveries injected into the ground, but there's not many places suitable for that. So we need to develop technologies to utilize the CO2 captured. That's going to take place. Well, talking about utilizing, I mean, have you been able to utilize the World Policy Conference to spread these ideas? I discussed that at the workshop on energy yesterday, and it was well received, but still that is a moving target. That's all, Masuda. Thank you so much. Thank you very much.
